I did put that "efficient" in there for a reason! Now, I'm not saying anything about how reasonable that idea is, but I can dream ;)

Well, I can't see how it could be less than the overhead involved in a sqrt(x) -> x.sqrt() indirection anyway.

When I read Mark's example, I wondered why he didn't simply write x**0.5 instead of sqrt(x), but it turns out it doesn't work on decimals.

cheers

Antoine.
